Silica Sand/Quartz Sand
Graded Natural Quartz Sand for Resin-Bound Flooring and Polymer Concrete
Washed and graded natural crystalline quartz sand for resin-bound flooring, polymer concrete and controlled decorative-composite trials. Buyers should qualify grading, cleanliness, moisture, color and binder wet-out in the actual resin and installation process.
Silica Sand/Quartz Sand
Low-Iron Natural Quartz Sand for Solar Glass Batch Trials
Natural crystalline quartz sand for solar-glass batch screening where the buyer must control iron, trace chemistry, particle-size distribution and melt behavior against a defined glass recipe. Grade selection follows the current TDS/COA and a customer melt trial.
Silica Sand/Quartz Sand
Quartz Sand for Terrazzo and Decorative Stone
Graded natural quartz sand for terrazzo, decorative stone and resin-bound surface formulations. Confirm particle size, color, chemistry and application fit against the project specification and trial.
Silica Sand/Quartz Sand
Natural Quartz Sand for Glass, Ceramics and Foundry
Natural crystalline quartz sand processed from selected quartz stone for glass, ceramic and foundry formulations. Mohs hardness 7, milky-white to translucent appearance and particle-size grading available to agreed requirements. Contact Changtong for grade-specific chemistry, sizing, samples and quotation.
